Abstract:

A method for autonomous vehicles to change lanes on a motorway may include steps of providing a computer system enabling an incoming vehicle that conducts lane change to negotiate with an incumbent vehicle that stays in its lane; generating first synchronous data on traffic density and traffic speed to the vehicles in both the transversal and longitudinal directions on the motorway; generating second synchronous data on traffic density and traffic speed to said vehicles for vehicles entering on the motorway and exiting the motorway; providing a summary of historical statistics on the first and second synchronous data to the vehicles; calculating a fair price of each lane of the motorway at a predetermined location, at a predetermined time and within a predetermined tolerance; and generating a protocol to change lanes, wherein said incoming vehicle pays said incumbent vehicle the fair price to move in front of the incumbent vehicle.

Abstract:

The present invention provides a new class of compounds useful for the modulation of beta-secretase enzyme (BACE) activity. The compounds have a general Formula I:wherein variables A, A, A, A, each of Rand R, Rand Rof Formula I, independently, are defined herein. The invention also provides pharmaceutical compositions comprising the compounds, and corresponding uses of the compounds and compositions for treatment of disorders and/or conditions related to A-beta plaque formation and deposition, resulting from the biological activity of BACE. Such BACE mediated disorders include, for example, Alzheimer's Disease, cognitive deficits, cognitive impairments, schizophrenia and other central nervous system conditions. The invention further provides compounds of Formulas II and III, and sub-formula embodiments thereof, intermediates and processes and methods useful for the preparation of compounds of Formulas I-III.
